Features you want for next iPhone/iOS

I want to know what you guys want in the next iPhone. Is it a better/bigger display? Better/bigger battery? More storage? Do you want a system overhaul for iOS? Let's hear it. I switched to the Note 2 because I wanted better battery and a huge screen (huge media junky) and while I miss a lot of features on iOS it's not making me come back until I see a few changes. Now don't get me wrong, I actually love the iPhone 5 and Apple (own an iPad and MacBook Pro), but I also love choice. So please tell me guys, what are some features you'd like to see both realistic and unrealistic (within the realm of reason, nothing like "I wish it'd fly me to Alaska").
